Login after recreate the data source

Hello,

I just try to recreate my data source with this document : https://help.sap.com/viewer/2e167338c1b24da9b2a94e68efd79c42/4.2.3/en-US/46986fd46e041014910aba7db0e91070.html.

My BI server is running on a Windows Server 2019 and my data source is on an Oracle Base which is on a linux server.

I make some test on a POC to prevent any future issues... So i volontarily break my data source with dropping some tables... And I use the procedure on the link I mentioned at the beginning. But after the success message, i let the SIA restart (about 1 hour) and i try to connect to the CMC with the admionistrator and no password. The window open the CMC about 4 seconds and close it. What's happen ? Did i forget a step to recreate my data source ? Could you help me please ?

Please note i have restarted the SIA & Tomcat several times.

Thanks,
